2 Claims.

This invention relates to containers, such as milk bottles, which areprovided with hoods to protect the mouths of the containers fromhandling. One object is to provide, in combination with a containerhaving an external top lip forming an abrupt underneath shoulder, a hoodthereon of the class comprising a crimped-skirted cap and a band bandingthe hood-skirt and the band whereof shall so coact with and be rem latedto said shoulder as to firmly secure the hood against slipping off thecontainer and which hood shall be so constructed that it may be readilyremoved from the container by a novel manual operation and withoutdisassociation or appreci able disturbance of the relation of the capand band to each other. Another object is to provide a hood of theindicated class which may be manufactured at little expense; be nestedwith others in quite compact order; and be readily applied by a singlepressure operation involving only a contraction of the hood intogripping relation to the container and with the use of a simple form ofattaching appliance.

In the best form, the skirt or the cap is crimped in a definite way, towit, with box pleats, which it is found permits the expansion of theskirt to be efiected more easily and uniformly than when the skirt iscrimped indiscriminately or even with simple pleats.

The band may be secured to the skirt in any way at substantially equallyspaced points circumferentially thereof. Thus, if it is a fiat band, byforming spurs or cleats therein which penetrate the skirt and areclinched to it. Or it may be secured to the skirt by a fillet of paperor other flexible material covering it circumferentially and glued orotherwise secured to the skirt.

In the drawing,

Fig. 1 is a side elevation of the hood before application to the bottle;

Fig. 2 is a view similar to Fig. 1 with the hood applied to the bottle;

Fig. 3 is a view similar to Fig. 2, illustrating the manner ofwithdrawing the hood;

Fig. 4 is a section on line 4-4, Fig. 2;

Fig. 5 is a fragmentary section on line 5-5, Fig.

Fig. 6 shows a modification; and

Fig. 7 is a side elevation of the top of the bottle. The bottle 1 hasthe conventional top lip 2 formed with an abrupt shoulder at 3. 4 is itssealing cap.

To form the cap 5 a disk of paper of the weight a or stock commonly usedfor bottle hoods now em- 1933, Serial No. 683,494

ployed is by suitable means developed to the truncated conical shapeshown by Fig. 1, thus to produce a top disk portion 5a and 2. dependingconical flaring skirt 5b. The skirt in the operation of forming the capbecomes crimped and this crimping is so performed that in horizontalsection a number of box-pleats 6 (Fig. 7) are developed.

Having the cap thus formed a non-resilient band '7, as of thin easilypliable, non-resilient metal, is fitted over and secured to the skirt.It being an important feature of our invention that the band should takeunder the abrupt bottle shoulder 3 when the hood has been applied to thebottle the position of this band should be such that when it is thusfitted over the cap its top edge will stand in approximately thathorizontal plane which is distanced from the top 5a of the capapproximately the same as the shoulder is from the top of the bottle, sothat it will bend the skirt underand against the shoulder, as at in Fig.2, when the assembly of bottle and hood is complete.

Either the band element or the cap element may have means to secure theband element to the skirt against axial displacement relatively to saidskirt. Thus in the form shown by Figs. 1 to 5 the band element hascut-out cleats or spurs 8 which are bent inward so as to puncture andclinch the skirt. And in the form shown by Fig. 6 the skirt of the caphas a flexible fillet or strip (as of stout paper) whichcircumferentially embraces the band and, being wider than the same, isglued at least below, and preferably also above it, to the skirt.

In any event, the skirt of the cap should be of such depth that when theband is in place the skirt will extend an ample distance, as shown,below the band so as to permit the thumb or forefinger to be enteredbetween the skirt edge and the bottle and a firm digital grip obtainedon such edge.

The improved unitary hood, comprising the cap and the band permanentlyunited, is applied to the bottle by tapping the bottle therewith andthen, by a suitable appliance, contracting the band and hence the skirtand so that the band will take under the shoulder 3 of the bottle, inwhich operation crim-ps 10 will be formed in the band at various points.The effective operation of the tool without its incidentally displacingthe element 7 downwardly with respect to the cap is insured by shapingsaid element to a form which is conical in the same direction as thecap-skirt.

To remove the hood the consumer inserts his finger or thumb between thebottle and the skirt Bill edge and pulls radially on the skirt to expandit and hence the band (repeating this operation at other points aroundthe bottle if necessary) and then by an upward pull slips the hood withthe band, which remains attached to the cap, off the bottle.

Having thus fully described our invention what we claim is:

l. The herein described generally symmetrical frustro-conical unitaryhood for a container having a top external lip forming an underneathshoulder, said hood comprising a flexible cap element having asubstantially conical flaring skirt and, in a zone removed from thelower edge of the skirt and to be below said shoulder when the capelement rests on and in capping relation to the container top, anon-resilient pliable element completely encompassing and snugly fittingthe skirt and itself substantially symmetrical and of uniform strength,one of said elements having at substantially uniformly spaced pointscircumferentially of said elements means to secure the band element tosaid skirt against axial displacement relatively to said skirt and saidpliable element, when the hood is placed in capping relation to thecontainer, being adapted to be crimped and thereby contract said skirtbelow said shoulder to less diameter than the latter and being alsoconical in the same direction as the skirt.

2. The herein described unitary hood for a container comprising aflexible cap, a non-resilient pliable element completely encompassingand snugly fitting the cap-skirt, and a flexible fillet extending aroundthe skirt and overlying said element and secured to the skirt at theside of said element adjoining the free edge of the skirt.
